refactoring async

- centralized skipping
- also fixed module name broken by previous refactor
- let action modules handle async processing
- moved async into base action class's module exec
- action plugins can now run final action as async
- actually skip copy if base skips
- fixed normal for new paths
- ensure internal stat is never async
- default poll to 10 as per docs
- added hint for callback fix on poll
- restructured late tmp, now a pipeline query
- moving action handler to connection as networking does
- fixed network assumption invocation is always passed
- centralized key cleanup, normalized internal var
- _supress_tmpdir_delete now in _ansible_xxx and gets removed from results
- delay internal key removal till after we use em
- nicer tmp removing, using existing methods
- moved cleanup tmp flag to mking tmp func
